Here is another important function help()

Screenshot follows:

>>> help()

Welcome to Python 3.7's help utility!

If this is your first time using Python, you should definitely check out

the tutorial on the Internet at https://docs.python.org/3.7/tutorial/.

Enter the name of any module, keyword, or topic to get help on writing

Python programs and using Python modules. To quit this help utility and

return to the interpreter, just type "quit".

To get a list of available modules, keywords, symbols, or topics, type

"modules", "keywords", "symbols", or "topics". Each module also comes

with a one-line summary of what it does; to list the modules whose name

or summary contain a given string such as "spam", type "modules spam".

help> math.pow

Help on built-in function pow in math:

math.pow = pow(x, y, /)

Return x**y (x to the power of y).

help> random.randrange

Help on method randrange in random:

random.randrange = randrange(start, stop=None, step=1, _int=<class 'int'>) method of
random.Random instance

Choose a random item from range(start, stop[, step]).

This fixes the problem with randint() which includes the

endpoint; in Python this is usually not what you want.
